SEAM COMPOUND PRESS Filed Dec. 15, 1950 INVENTOR. 614 94 2 BUN/(6A? United States Patent SEAM COMPOUND PRESS Carl D. Bunker, North Haven, Maine Application December 15, 1950, Serial No. 200,938

1 Claim. (Cl. 183.5)

This invention relates to dispensing tools for calking and the like, and more particularly to an improved device for calking seams of wooden boats, cracks in structures, such as floors, or walls, and the like, with seam compound, such as putty or calking.

A main object of the invention is to provide a novel and improved calking device, said device being very simple in construction, being easy to operate, and providing efiicient disposition of calking in seams so as to properly and completely fill the seams.

A further object of the invention is to provide an improved device for dispensing calking compound and the like, said device being inexpensive to manufacture, being readily accessible for refilling, being sturdy in construction, and providing a very great saving in time and labor in calking operations on boats, building structures, and the like.

Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:

Figure l is a side elevational view, partly in longitudinal cross-section, of an improved calking device constructed in accordance with the present invention;

Figure 2 is a fragmentary, side elevational view of the device of Figure 1 taken from the opposite side thereof;

Figure 3 is a bottom plan view of the device of Figures l and 2; and

Figure 4 is an enlarged cross-sectional detail view taken on the line 44 of Figure 1.

Referring to the drawings, the illustrated device is designated generally at 11 and comprises a longitudinally elongated, rectangular housing 12 having an elongated, vertical side wall 13, front and rear vertical end walls 14 and 15 secured to the wall 13, as by the fastening screws 15' and 16', and an opposite side wall 16 detachably secured to the end walls 14 and 15. As shown in Figure 2, the marginal end portions of the side wall 16 are formed with outwardly flared longitudinal notches 17, 17 at one end and longitudinal notches 18, 18 at the other end. The side wall 16 is fastened at one end by screws 19, 19 extending through the notches 17, 17 into the end wall 14 and is secured at the other end by wing bolts 15' which extend transversely through the Wall 13, the end wall 15, and the notches 18 in the side wall 16, wing nuts 20 being threadedly engaged on said bolts 15'. It will be readily apparent that by loosening the Wing nuts 20, the side wall 16 may be removed by first moving it to the left to disengage it from bolts 15' and then to the right, as viewed in Figure 2, providing access to the interior of the housing.

As shown, the housing 12 is provided with a top wall 21. The lower portion of the side wall 16 is bent downwardly and inwardly, as shown in Figure 4, at 22, to define a bottom wall which terminates adjacent to, but spaced from, the lower edge of the side wall 13, to define a discharge slot 23. Secured to the lower marginal portion of the side wall 13 are a pair of depending, flat guide blades 24, 24 which are adapted to be inserted within the crack or seam to be filled so as to accurately position the slot 23 over said crack or seam. Slidably positioned inside the housing 12 is the rectangular piston 25, and rigidly secured to said piston is the vertical piston rod 26 which extends slidably through the top wall 21 of housing 12. Designated at 27 is a lever which is pivotally secured at its intermediate portion, as shown at 28, to the top end of the piston rod 26. One end of lever 27 is connected to a longitudinal extension 29 of the side wall 13 by a link bar 30. The other end of lever 27 is provided with the handle portion 31. Rigidly secured to the end wall 15 of housing 12 is a longitudinally extending handle 32 which is disposed adjacent to the handle member 31 and which is arranged so that when the operator forces the handle member 31 toward the handle member 32, the piston 25 will be forced downwardly inside the housing 12. A supply of calking compound is provided in the housing 12 beneath the piston 25, and the downward pressure exerted on said compound by the piston 25 forces said calking compound out of the lower end of the housing through the discharge slot 23 in the form of a fiat ribbon of a length equal to the length of slot 23. As above explained, the guide blades 24, 24 are inserted in the seam or crack to be filled, whereby the calking compound discharged through the slot 23 is guided directly into the crack or seam. Consequently, there is no waste of material and the calking compound is discharged directly into the crack or seam and will completely fill same. The relatively great cross section of the housing and of the piston therein as com pared to that of the slot 23, which is of approximately the width of the average seam or crack to be filled, provides unusual capacity for calking compound and discharge of the calking compound through the slot 23 at relatively high pressure.

As above described, where it is necessary to replenish the supply of calking compound, in the apparatus, the wing nuts 20 are loosened, whereby the wall 16 may be detached to provide access to the interior of housing 12.

While a specific embodiment of an improved dispensing device for calking compound and the like has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claim.

What is claimed is:

In a seam calking device, a longitudinally elongated housing adapted to be moved endwise along a seam to be calked, said housing comprising laterally spaced side walls and end Walls, said side walls having lower edges, the lower edge of one of said side walls depending below the lower edge of the other side wall, a declining bottom wall fixed on the lower edge of said other side wall, said bottom wall having a free lower edge on a level with and laterally spaced from the lower edge of said one side wall and therewith defining a calking compound discharge slot extending longitudinally of the housing, a piston fitting said housing and movable toward said slot for discharging calking compound through the slot, said one side wall having a longitudinal extension reaching beyond the adjacent housing end wall, and said piston having a piston rod rising above the housing, an operating lever extending longitudinally of said housing, said lever having an end pivotally mounted on said extension and a free end, and means pivoting an intermediate part of said lever to said piston rod, and guide blades mounted on the laterally inward side of said one side wall and on said extension and depending below the free edge of said one side wall.
